Wire is just wire when source impedance, load impedance and wire

Even at RF frequencies, only ONE end (either end) needs to be properly matched to Zo and the reflection will be absorbed and there will be no frequency response issues (other than the inherent loss of the cable increasing with frequency).
I agree, at audio frequencies and practical lengths, the R is the only issue.
